What Is This?

Is it a newly published, real-life Pokemon, or maybe a new character addition to Black Mesa? Maybe it's a new plant discovered in the depths of the Amazonian rainforest? Or perhaps it's just a close up of a flesh eating parasite, or even a living spaceship from Farscape?

It may look very alien-like but it is, in fact, the easy to pronounce, Glaucus Atlanticus, also known as Blue Ocean Slug, found off the coast of South Africa, Australia and Mozambique. While it's pretty cool-looking, the surface you're looking at there is actually the 'foot' of the slug, meaning it floats upside down for the whole of its life; the poor little guy just can't catch a break.
